My local repair center agreed to install the Nikasil plated cylinder that I purchased for my Husqvarna 350 chain saw. It was a successful repair however,...
Afterwards, I discovered this and it gives me concern.
" with Nikasil cylinder bore linings are particularly vulnerable to fuel (gasoline or petrol) with a high sulfur content.
The sulfur in the fuel breaks up the Nikasil lining in the cylinders, thus causing a loss of compression. Once the lining is damaged, excessive bore wear of the soft, underlying alloy occurs very quickly. Some Nikasil engines have failed in as little as 30,000 miles. And the effect is cumulative, so if the engine has ever been run on high sulfur fuel, the damage may already have been done and premature bore wear may result.
Some symptoms of the Nikasil problem are rough running at idle and difficult cold starting, both due to loss of compression. In severe cases, the loss of compression is so bad that the engine loses power."
